Halcyon RB80

Halcyon RB80‏‎ is a rebreather designed for technical diving. It is a semi-closed circuit rebreather, which means it recycles a portion of the exhaled gas. The Halcyon RB80‏‎ is known for its robustness and reliability, making it a popular choice among technical divers.

Design and Function

The Halcyon RB80‏‎ is designed with a focus on simplicity and reliability. It uses a semi-closed circuit design, which means that a portion of the exhaled gas is recycled and reused. This design reduces the amount of gas that is wasted, making the rebreather more efficient. The unit is also designed to be easy to use, with a straightforward interface and clear indicators.

The rebreather uses a scrubber to remove carbon dioxide from the exhaled gas. The scrubber is filled with a chemical absorbent, which reacts with the carbon dioxide to remove it from the gas. The gas is then returned to the breathing loop, ready to be inhaled again.

Use in Technical Diving

The Halcyon RB80‏‎ is commonly used in technical diving, a type of diving that goes beyond the limits of recreational scuba diving. Technical diving often involves diving to greater depths, for longer periods of time, and in more challenging environments. The efficiency and reliability of the Halcyon RB80‏‎ make it well-suited to these demanding conditions.

Technical divers often use the Halcyon RB80‏‎ for cave diving and wreck diving. These types of diving require a reliable and efficient rebreather, as the diver may be far from the surface and in a challenging environment.

Safety Features

The Halcyon RB80‏‎ includes several safety features to protect the diver. These include a manual addition valve, which allows the diver to add gas to the breathing loop if needed. The unit also includes a pressure relief valve, which prevents the pressure in the breathing loop from becoming too high.
